Dohc Zc in a 91 si

Quick question.

Will the JDM DOHC ZC engine drop right into a 91 civic si with an 88 -89 integra ecu. I've been told yes but i've been shopping around online for one and alot of the places are selling them as applications for 92-95 civics.

Help a botha out cuase my head hurts:confused: I just wanna make sure im not gonna spend all this money for something that won't fit.

thanks

Yes it drops right in! I dont know about the 92-95 civic zc but you'll need the one from the jdm crx si 88-91 cable trans and thats non obd.
